Introduction


cont.
ARRB has been assisting the resource industry by:

conducting site-based road safety audits

auditing heavy vehicles routes (public roads)

developing traffic management plans

undertaking crash investigations
Presenter: Traffic safety engineer with mining
background and experience in traffic risk assessments

RISK
Department of Consumer

Resources Safety
8
Why are road safety and traffic management
important?

Form part of an overall risk management strategy

Minimise injury and property damage

Ensure people travel safely while at work and on their
journeys to and from work

(Reduce downtime, cost and inefficiency)

Regulatory framework
Mines Safety and Inspection Act 1994


Promote and improve the safety and health of persons at mines
Onus is on the employer to ensure that, as far as is practicable,
employees are not exposed to hazards or do not do hazardous work
without appropriate personal protective equipment and equipment as is
practicable to protect them against those hazards, without any cost to the
employees
Each person who works on a mine is responsible for:


their own safety
the safety of others affected by their actions or inactions
A motor vehicle used as part of work is considered to be a workplace

What is risk?
RISK = Exposure x Likelihood x Severity
Exposure = traffic volumes
Likelihood = length x general & relative risk x influencing factors
Severity = historical average of a crash type’s severity (consequences)
Department of Consumer
and Employment Protection
Resources Safety
11
How can we reduce risk?

Reduce exposure


Reduce likelihood





Access control
Road design (alignment, cross section, etc.)
Maintenance and repair of roads
Training / permits
Segregation between vehicle types
Reduce severity



Speed management
Vehicles standards (ROP, FOP, load restrains, etc.)
Clear zones and barriers

Road design

Alignment

Width

Gradients

Profile

Construction practices

Unsealed roads
 Competency and operator training (design manuals, standards,
practices)
 Lifecycle economics
 Drainage
 Dust suppression
Department of Consumer

Resources Safety
14
Intersection design

Sight distances / visibility (consideration for different
vehicle types and surface conditions, remove road side
objects obscuring visibility)

Alignment (preference to intersections at right angles)

Right of way controls (Give Way / Stop signage)

Conspicuousness (advance warning signs, lighting,
hazard board markers at the terminating leg)

Preference for “T” junctions over four-way crossovers
Department of Consumer
and Employment Protection
Resources Safety
15
Right-of-way rules


Consistent with normal road conditions and Australian road
rules
Intersections should be posted with “Give way” or “Stop”
signage

No differentiation between vehicle types

Only exception — emergency vehicles

Alternative right of way arrangements require a risk
assessment
Department of Consumer
and Employment Protection
Resources Safety
16
Pavement design and road surface condition

Poor pavement design practices lead to cracks, rutting,
potholes and other failures

Roads should be kept free of loose material

Regular / as-required clean ups (sweeping)
Department of Consumer
and Employment Protection
Resources Safety
17
Clear zones

Horizontal width of space on the side of a road that
should be free of hazards (i.e. should be safely
traversable by errant vehicles)

Width depends on the speed and geometry (1 metre to
about 3 metres)

Where clear zone cannot be achieved:

Hazards should be signed and marked

Protected by barriers
Department of Consumer
and Employment Protection
Resources Safety
18
Safety barriers

Can become hazards themselves

Should be installed to applicable standards and specs (e.g.
minimum effective length 28 metres, 600 mm deflection)

A list of approved W-beam barriers for use in WA can be
obtained from Main Roads WA

No barrier has been tested on heavy vehicles

Should have approved end treatments

Reflectors
Department of Consumer
and Employment Protection
Resources Safety
19
Separation of heavy and light vehicles
Pedestrians, heavy vehicles and light vehicles should be
separated wherever possible (or interaction minimised)

Physical separation – (semi)permanent barriers,
separate road networks, parking facilities

Time separation – management process aimed at
restricting access to certain vehicles into certain areas at
certain times (i.e. no deliveries during shift change
hours, activities restricted to night shifts where traffic
volumes are generally lower)

Lighting
Common problems




Glaring
Dark spots
Inadequate lighting of pedestrian
facilities
Inadequate lighting of parking
facilities
Regular inspections and reporting

PEDESTRIANS
Department of Consumer
and Employment Protection
Resources Safety
22
Pedestrians — desire lines and route planning

Walking is always present and safe walking
should be encouraged

Identify main desire lines and match with
appropriate infrastructure (footpaths, crossings)

Separation and protection from vehicles

Monitor usage
Department of Consumer
and Employment Protection
Resources Safety
23
Footpaths

1.5-2.0 metres wide

Ideally raised (kerbed)

If level with roads, mark footpaths with paint

Provide lighting

Marked crossings (zebras) only at locations with high
pedestrian activity. Most crossings should be unmarked
but signposted
Department of Consumer
and Employment Protection
Resources Safety
24
Footpaths cont.

No parking on footpaths allowed

Protect pedestrians with safety guardrail

Pedestrians should be encouraged to use footpaths

Assess and address tripping hazards

(High visibility) PPE should be worn at all times
Department of Consumer

25
DELINEATION
Department of Consumer
and Employment Protection
Resources Safety
26
Delineation — colour coding

Delineation of areas of specific activities (walkways,
laydown, working, hazards, etc.)

Should be standardised and consistent across operations
Department of Consumer
and Employment Protection
Resources Safety
27
Delineation — guide posts

Delineate the road formation

Red on the left, white on the right

Installation:
 Roads: 150 metres on straight section, two pairs should be
visible at all times (depends on the speed), about
1.5metres from road formation
 Haulage roads: 50 metres on flat roads, and 30 metres on
curves; 1.5-2 metres height, 0.5-1 metres from edge of
road

Auditing of guide post condition (cleaning, repairing, replacing)
Department of Consumer

TRAFFIC SIGNS
Department of Consumer
and Employment Protection
Resources Safety
29
Traffic signs

Principles for installation:
 Familiarity
 Consistency
 Meet expectation
 Relevancy
 Follow relevant standards (AS 1742, Main Roads WA
guidelines, Road Rules)

Reflectivity (AS 1906 as a minimum, high reflectivity
materials for dusty conditions)

Use Size B or Size C signs
Department of Consumer
and Employment Protection
Resources Safety
30
Use of non-standard signs

Road users respond best to standard traffic controls

Minimise the use of non-standard signs
 Graphical representation
 Up to 5 words on up to 5 lines
 Font size depends on speed

Replace non-standard signs

Implement an approval system for installing signs

Issues with traffic signs

Issues
 Faded, damaged, non-reflective signs
 Dirty
 Obscured by vegetation
 Missing
 Small size
 Obsolete
 Signage clutter

Implement a regular monitoring and maintenance program
Department of Consumer
and Employment Protection
Resources Safety
32
Speed signs

Should be in multiplies of 10 km/h

Installed on the left side of the road


Ideally on both sides of the road
On long stretches of road, repeater signs installed
at spacings of 500 metres
Department of Consumer
and Employment Protection
Resources Safety
33
Speed management

Appropriate speed limits

Consistency

Practicality

Relevancy



Prepare speed zone maps

Provision for pedestrian corridors
Lighting as appropriate
Reverse parking might not be the best solution for all
